Ever drive around the neighborhood to see some of the lawn look great and other not so nice. The good looking lawns have sharp blades on their mower and are cut weekly using deference paths so not to create ruts. The costs of having the lawn mower blades sharpened and balanced most times are more than buying new. Sharp blades even save on wear and tear on the belts, pulleys, and mandrels saving you money. So check your mower you may need new blades. After a few cuts people will say wow look at that lawn.
